  • TREATMENT OF OSTEOARTHRITIS SECONDARY TO ACETABULAR DYSPLASIA BY TOTAL HIPARTHROPLASTY

    【Abstract】 Objective To evaluate the flexibil ity of the treatment of osteoarthritis secondary to acetabular dysplasiaby total hip arthroplasty (THA) , in which the acetabular component is placed in the true acetabulum and femoral osteotomy is not performed. Methods From January 1999 to December 2005, 35 THA procedures were performed in 32 patients with 35 hips, including 6 males with 7 hips and 26 females with 28 hips, with the average age of 53 years (ranging from 28 years to 72 years). On the basis of Crowe classification, type I included 10 patients with 11 hips, type II included 14 patients with 15 hips, type III included 5 patients with 6 hips, and type IV included 3 patients with 3 hips. All patients experienced severe pain and dysfunction. In 19 cases, the leg length discrepancy was from 3 cm to 6 cm. The Harris score was 41.49 ± 10.13 before the operation. In all procedures, the soft tissue was released entirely and the acetabular component was placed in the true acetabulum, but femoral osteotomy was not performed. Results The average operation time of unilateral THA was 50 minutes. All patients were given transfusion from 2 U to 4 U. All incisions healed at the first stage. After the operation, the leg was lengthened 2-6 cm, and the two legs were equally long. The follow-up lasted for 12 to 60 months. The Harris score was 84.71 ± 9.34 after the operation, showing statistically significant differece (P lt; 0.05). According to cl inical outcomes and X-ray films, no dislocation, femoral fracture, femoral or sciatic nerve palsy was detected. Conclusion It is effective to use THA procedures for osteoarthritis secondary to acetabular dysplasia. If the soft tissue is released entirely, the leg will be lengthened 4-6 cm without nerve palsy.

  • RELATIONSHIP BETWEEN INITIAL STABILITY AND INFECTED LOOSENING OF TOTAL HIP ARTHROPLASTY PROSTHESIS

    Objective To investigate the relationship between the initial stabil ity and infected loosening of the total hip arthroplasty (THA) prosthesis. Methods From January 2000 to December 2008, 110 cases (110 hips) were treated with THA revision. Among them, 15 cases (15 hips) were confirmed infected loosening. There were 8 males and 7 females with anaverage age of 62 years (range 42-75 years). The infected signs were found from 6 months to 2 years after initial THA. All of them had Tsukayama type IV and late infection, including 6 cases of acetabular infected loosening (5 cases of one-stage and 1 case of two-stage acetabular revision), 7 cases of simple infected loosening of femoral prosthesis (4 cases of one-stage and 3 cases of twostage femoral prosthesis revision), and 2 cases of joint capsule infection and sinus without prosthesis loosening (debridement and continuous irrigation). Results All incisions healed by first intention. Fifteen patients were followed up for 12 to 36 months (average 24 months). In 13 cases of revision, postoperative X-ray films showed that femoral acetabular prostheses were in good position, and had no cl inical and imaging infective signs of loosening. In 2 cases of joint capsule infection, sinus recurred 6 months postoperation without hip joint pain, the function of weight-bearing and walking of hip joint was normal. Harris score increased from preoperative average of 42 to postoperative average of 85; the results were excellent in 4 cases, good in 7 cases, and fair in 4 cases. Conclusion The infection of THA may occur in the whole joint, half-joint or just in joint capsule. The initial stabil ity of the prosthesis would affect the long-term survival of the prothesis. If the prosthesis initial stabil ity is obtained, even if there are infective factors, infections would also be l imited.

  • 一期人工全髋关节置换治疗髋臼骨折合并股骨头颈骨折

    目的  总结髋臼骨折切开复位内固定、一期人工全髋关节置换治疗髋臼骨折合并股骨头或颈骨折的临床疗效。  方法   2005 年 1 月- 2008 年 12 月,采用髋臼骨折切开复位内固定、一期人工全髋关节置换治疗髋臼骨折合并股骨头、颈骨折 6 例。男 5 例,女 1 例;年龄 45 ~ 65 岁。高处坠落伤 2 例,车祸伤 4 例。均为新鲜闭合骨折。受伤至入院时间为 2 h ~ 2 d。其中 2 例合并股骨颈头下型骨折,4 例合并髋关节后脱位及股骨头骨折,2 例合并颅脑损伤。   结 果  手术时间50~90 min,术中失血量400~800 mL,术中输压积红细胞2~4 U。术后切口均Ⅰ期愈合,无感染、血栓形成等并发症发生。5 例患者获随访,随访时间 9 ~ 36 个月,平均 20 个月。髋臼骨折于术后 8 ~ 16 周达骨性愈合,无感染及假体松动发生。末次随访髋关节功能根据 Harris 评分为 75 ~ 95 分,获优 1 例,良 2 例,中 2 例。  结论  一期髋臼骨折内固定、人工全髋关节置换治疗髋臼骨折脱位合并股骨头、颈骨折,可减少股骨头缺血性坏死、创伤性关节炎等并发症,避免二次手术,缩短住院时间。
